Topical Therapy

Prescription topical medication is the first line of defence on early stage psoriasis, or can be used as an adjunct to other treatment options if your psoriasis has progressed. Your specialist will discuss the use of topical prescriptions and the 5 most common medications that we use today.

 

Systemic & Biologic

Prescription oral medication is the last line of defence on late stage psoriasis that is not relieved by other treatment modalities. To access oral medication, all other treatments must have failed and a severity of psoriasis must be indicated.

 

UVB Phototherapy as a Treatment for Psoriasis

Psoriasis, a chronic autoimmune skin condition, casts its shadow over millions, impacting not only physical health but also the emotional well-being of those affected. Amidst the various treatment modalities available, UVB phototherapy stands out as a beacon of hope. This targeted use of ultraviolet B light has emerged as a valuable and effective tool in managing psoriasis, offering relief from the visible symptoms, and contributing to an improved quality of life. In this exploration, we delve into the mechanisms, benefits, and considerations surrounding UVB phototherapy as a frontline treatment for psoriasis.

Understanding UVB Phototherapy

UVB phototherapy involves exposing the skin to ultraviolet B light, a specific range of wavelengths within the ultraviolet spectrum. This controlled exposure, often administered in a medical setting, harnesses the therapeutic properties of UVB light to alleviate the symptoms of psoriasis. The treatment is carefully calibrated to balance effectiveness with safety, ensuring a targeted approach to managing this complex skin condition.

 

The Mechanism of Action

Suppressing Immune Response:

Psoriasis is fundamentally an autoimmune disorder, with the immune system mistakenly attacking healthy skin cells. UVB phototherapy works by suppressing the aberrant immune response, reducing the rapid turnover of skin cells and alleviating the characteristic red, scaly patches.

Modulating Inflammation:

Chronic inflammation is a hallmark of psoriasis, contributing to the formation of plaques and exacerbating symptoms. UVB phototherapy helps modulate inflammation, calming the overactive immune response and providing relief from the inflammatory burden associated with psoriasis.

Slowing Cell Proliferation:

UVB light targets the hyperproliferation of skin cells, slowing down excessive growth and turnover. By normalising cell proliferation, UVB phototherapy contributes to a smoother skin surface, reducing the visible signs of psoriasis.

 

Different Forms of UVB Phototherapy

Broadband UVB:

Broadband UVB phototherapy employs a broad spectrum of UVB wavelengths, providing a versatile and effective treatment for various forms of psoriasis. While it requires more frequent sessions compared to narrowband UVB, it remains a valuable option for individuals with widespread or stubborn psoriasis lesions.

Narrowband UVB:

Narrowband UVB phototherapy utilises a more focused range of UVB wavelengths, optimizing the therapeutic effects while minimising potential side effects. This targeted approach allows for shorter treatment sessions and has become a preferred choice for many dermatologists due to its efficiency and safety profile.

 

Benefits of UVB Phototherapy for Psoriasis

Efficacy:

UVB phototherapy has demonstrated high efficacy in managing psoriasis symptoms. The controlled exposure to UVB light targets key mechanisms involved in psoriasis pathogenesis, leading to a visible reduction in plaques, scaling, and erythema.

Targeted Treatment:

The ability to focus UVB light on specific areas allows for a targeted treatment approach. Dermatologists can tailor the exposure to address individual lesions or affected regions, optimizing the therapeutic impact while minimising potential side effects on unaffected skin.

Minimal Systemic Absorption:

Unlike some systemic medications, UVB phototherapy has minimal systemic absorption. This characteristic reduces the risk of widespread side effects, making it a suitable option for individuals who may not tolerate or prefer to avoid systemic treatments.

Safety Profile:

UVB phototherapy is generally considered safe when administered under the supervision of healthcare professionals. The controlled and monitored exposure helps minimise the risk of adverse effects, and the treatment can be adjusted based on individual response and skin type.

Combination Therapy:

UVB phototherapy can be used in combination with other psoriasis treatments, enhancing overall efficacy. This versatility allows dermatologists to customize treatment plans, combining UVB phototherapy with topical agents or systemic medications for a comprehensive approach.

 

Considerations and Precautions

Skin Type and Sensitivity:

Individual variations in skin type and sensitivity play a crucial role in determining the appropriate dosage of UVB light. Dermatologists carefully assess these factors to tailor the treatment and minimise the risk of sunburn or other adverse reactions.

Frequency and Duration of Treatment:

The frequency and duration of UVB phototherapy sessions are individualised based on the severity of psoriasis, skin type, and the specific type of UVB treatment employed. Regular monitoring allows for adjustments to ensure optimal therapeutic effects.

Potential Short-term Side Effects:

While UVB phototherapy is generally well-tolerated, short-term side effects such as redness, itching, or dryness may occur. These effects are usually mild and transient, resolving with continued treatment.

Long-term Safety:

The long-term safety of UVB phototherapy has been well-established, but ongoing research aims to further refine protocols and ensure its safety profile. Dermatologists carefully balance the benefits and risks, monitoring patients for any signs of long-term adverse effects.

 

Patient Experience and Compliance

Convenience:

UVB phototherapy sessions are typically conducted in outpatient settings, providing a convenient option for individuals seeking relief from psoriasis symptoms without the need for hospitalization. This accessibility contributes to improved patient compliance.

Positive Psychological Impact:

Beyond its physical benefits, UVB phototherapy often has a positive psychological impact. Visible improvements in skin appearance can boost self-esteem and reduce the emotional toll of psoriasis, contributing to an overall improved quality of life.

Home Phototherapy Units:

In some cases, dermatologists may recommend home phototherapy units for ongoing treatment. These units allow for greater flexibility and convenience while maintaining the efficacy of UVB phototherapy under the guidance of healthcare professionals.

 

Conclusion

UVB phototherapy stands as a powerful and targeted treatment option for individuals grappling with the challenges of psoriasis. Its efficacy in suppressing the immune response, modulating inflammation, and slowing cell proliferation makes it a cornerstone in the management of this chronic autoimmune condition. From broadband to narrowband UVB, the versatility and safety profile of this treatment contribute to its widespread use in dermatological practices.

As we unlock the illuminating promise of UVB phototherapy, it is crucial to acknowledge its role not only in alleviating visible symptoms but also in enhancing the overall well-being of individuals affected by psoriasis. The ongoing refinement of treatment protocols, considerations for individual variations, and the positive impact on patient compliance underscore the evolving landscape of UVB phototherapy as a dynamic and integral component in the multifaceted approach to managing psoriasis. Through the careful application of light, we continue to illuminate the path toward relief and improved quality of life for those navigating the complexities of psoriasis.
